20.500.12556/DKUM-98485 DFB vlakenski laser z uporabo aktivnega vlakna, dopiranega z erbijem magistrsko delo DFB fiber laser using erbium-doped active fiber Magistrsko delo opisuje zasnovo, realizacijo in eksperimentalno karakterizacijo vlakenskega laserja s porazdeljeno povratno zvezo, katero sestavljata vlakenska Braggova rešetka in Sagnacovo zrcalo. Namen naloge je bil razviti učinkovit, stabilen in cenovno ugoden laserski sistem, ki temelji na standardnih telekomunikacijskih komponentah. V okviru dela je bil kot aktivni medij uporabljen z erbijem dopiran kos optičnega vlakna, ki omogoča lasersko sevanje v okolici valovne dolžine 1550 nm, kar ustreza tretjemu telekomunikacijskemu oknu. Laserski resonator je bil realiziran z uporabo vlakenske Braggove rešetke in Sagnacovega zrcala, medtem ko je bilo črpanje zagotovljeno z lasersko diodo, katere valovna dolžina je sovpadala s telekomunikacijskimi kanali 3. telekomunikacijskega okna, kar je omogočilo izbiro uveljavljenih in cenovno dostopnih telekomunikacijskih diod. Posebna pozornost je bila namenjena analizi posameznih komponent laserske proge ter njihovemu vplivu na učinkovitost, izhodno moč in spektralne lastnosti laserja. Rezultati dela kažejo, da je mogoče z ustrezno izbiro in optimizacijo komercialno dostopnih komponent izdelati vlakenski laser s povratno zvezo z zadovoljivo koherenco in stabilnim delovanjem, primeren za senzorske aplikacije. This master’s thesis describes the design, realization, and experimental characterization of a distributed feedback (DFB) fiber laser, employing a fiber Bragg grating and a Sagnac mirror. The aim of the work was to develop an efficient, stable, and cost‐effective laser system based on standard telecommunication components. Within the scope of the work, a section of erbium‐doped optical fiber was used as the active medium, enabling laser emission in the vicinity of the 1550 nm wavelength, corresponding to the third telecommunication window. The laser resonator was realized using a fiber Bragg grating and a Sagnac mirror, while optical pumping was provided by a laser diode whose emission wavelength coincided with telecommunication channels within the third telecommunication window. This approach enabled the use of well‐established and commercially available telecommunication laser diodes. Particular attention was devoted to the analysis of individual components of the laser cavity and their influence on efficiency, output power, and spectral characteristics of the laser. The results demonstrate that, through appropriate selection and optimization of commercially available components, it is possible to realize a fiber laser with distributed feedback exhibiting satisfactory coherence and stable operation, suitable for sensing applications.
